Features

100% Rust
Powered by the Rayon library for high parallel perfomance
Supported on Unix-based platforms
Extremely fast at synchronizing directories with large quantities of files
Multithreaded copy, remove, and sync
A progress bar using indicatif

Copy

use lms_lib::{core, parse::Flag};
use std::path::Path;

main () {
	let src = Path::new("/foo/bar/hello.txt");
	let dest = Path::new("/bar/foo/hi.txt");
	core::copy(&src, &dest, Flag::empty())?;
}

Sync

use lms_lib::{core, parse::Flag};
use std::path::Path;

main () {
	let src = Path::new("/foo/bar/hello.txt");
	let dest = Path::new("/bar/foo/hi.txt");
	core::synchronize(&src, &dest, Flag::empty())?;
}

Remove

use lms_lib::{core, parse::Flag};
use std::path::Path;

main () {
	let target = Path::new("/bar/foo/hi.txt");
	core::remove(&target, Flag::empty())?;
}

Benchmarks

Using hyperfine on an Intel i7-8550U with the following 2 test folders,

Directory Directory Size Number of Files
1 88MB 7262
2 105MB 252
Command Directory Time
lms sync 1 179.1 ms ± 5.1 ms
rsync -r --delete 1 717.8 ms ± 41.1 ms
lms cp 1 117.3 ms ± 3.6 ms
cp -r 1 283.4 ms ± 13.2 ms
lms rm 1 147.6 ms ± 8.6 ms
rm -rf 1 180.7 ms ± 4.3 ms
---------------------- --------------- -----------------------------
lms sync 2 101.2 ms ± 24.8 ms
rsync -r --delete 2 442.2 ms ± 19.6 ms
lms cp 2 33.8 ms ± 2.8 ms
cp -r 2 143.5 ms ± 18.8 ms
lms rm 2 10.0 ms ± 2.8 ms
rm -rf 2 27.4 ms ± 0.8 ms

Of course, these benchmarks can be highly dependent on CPU and IO devices.
